Mavic UST tubeless for hassle free tire install and removal. Mavic have standardized tire and rim size to provide the perfect fit. We have tested this product and it's simply amazingly easy to work with.

The Mavic Ksyrium Pro has for many years been the pinnacle of alloy road wheels for all round performance, reliability and comfort and now tubeless its one step better.

Strong and stiff

Equally adept on fast, rolling roads or mountain terrain, the Ksyrium Pro UST delivers comfort and performance for a variety of riding conditions. Key updates include a UST tubeless compatible rim. When combined with our new 25mm Yksion Pro UST tubeless tires, the result is an 15% increase in rolling efficiency at equal tyre pressure. Or 5% rolling resistance improvement with 1bar /15PSI lower pressure to get extra comfort and grip. Other major updates include redesigned lighter hub shells, the implementation of our fast engagement Instant Drive 360 hub and new automatic adjustment of the bearing preload for long terms smoothness with no lay. Still laced with our proprietary Zicral alloy spokes that are stiffer, stronger and lighter than traditional stainless steel spokes. The Isopulse lacing pattern (radial lacing on the drive side) allows a more balanced spoke tension for a stiffer, more stable wheel. Fore drilling creates the strongest possible connection between rim and spokes, increasing stiffness by about 20%, and makes tubeless super easy to use, without the need for a rim tape. Each part of the rim is precisely machined using just the right amount of material to provide stiffness and strength, while maintaining weight at only 400g. All in all, the total wheel weight is down to an impressive 1420g.

I relaced the factory Aksium wheelset with these and there is a big difference. Very smooth and comfortable set, better acceleration and higher average speed. Will buy again! Glory Cycles has the best pricing
